    Changes (2 July 2026) to the version 4.80:

    - Compatibility to GNAT 16.1.1. This GNAT 16.1.1 has the recurring
    issue/bug related to the visibility of names from formal generic packages;
    - Constant expression folding was added to Ada expression parser (Parsers.Generic_Ada_Parser). Folding is optional. If enabled
    expressions in universal types and constant Boolean expressions are
    folded. e.g. 1 + 2 + A (5) -> 3 + A (5);
    - The subprograms Get, Put, Value were added to the package Parsers.Multiline_Source;
    - The call-back On_Success was added to the Generic_Lexer's parser;
    - The procedures Mark and Release were added to the package Parsers.Generic_Lexer;
    - The package Stack_Storage.Text_IO was added to output stack pool
    statistics;
    - Parameter Message was added to the procedure Put_Line of the package Parsers.Generic_Source.Text_IO;
    - Ada expression parser supports raise-statements outside immediate pair
    of parentheses;
    - Checking positional and named aggregates was added in the Ada
    expression parser;
    - Checking positional and named parameters was added in the Ada
    expression parser;
    - Array objects were added to the declare expressions in the Ada
    expression parser;
    - Aspects recognition was added to the declare expressions in the Ada expression parser;
    - Subtype marks and indications were added in the Ada expression parser;
    - Attributes were added in the Ada expression parser;
    - Target name @ support was added in the Ada expression parser;
    - The parser can start with the first operand already recognized;
    - An ability to parse an expression in parenthesis with a consumed left parenthesis was added;
    - Comparisons of Unbounded_Integer bug fixed;
